Geauga County prosecutor David Joyce announced the charges against Thomas "T.J." Lane, the accused Chardon High School shooter. Lane allegedly opened fire with a stolen semi-automatic pistol at Chardon High school as students gathered in the cafeteria early Monday morning, MSNBC reported.

Lane is also charged with two counts of attempted aggravated murder and one felony count of assault, according to CBS News.

Prosecutors have already stated that they will attempt to try the boy as an adult, which could result in a life sentence if Lane is found guilty. If Lane is convicted of the juvenile counts, he will face only a few years of detention, the Associated Press reported.

TJ Lane

T.J. Lane smirks as he listens to the judge during sentencing Tuesday, March 19, 2013, in Chardon, Ohio. Lane, was given three lifetime prison sentences without the possibility of parole Tuesday for opening fire last year in a high school cafeteria in a rampage that left three students dead and three others wounded. Lane, 18, had pleaded guilty last month to shooting at students in February 2012 at Chardon High School, east of Cleveland. Investigators have said he admitted to the shooting but said he didn't know why he did it. Before the case went to adult court last year, a juvenile court judge ruled that Lane was mentally competent to stand trial despite evidence he suffers from hallucinations, psychosis and fantasies.
